Is the harness where it connects to the engine the same?

Re: Wiring harness compatabilty

The only difference I can think of might be that I think the Fat Fifty has a charging system and the Big Twin probably doesn't. The end result is the 50 plug may have two more pins in it than the one on the 35... But, after 50+ years, who knows what may have been mixed and matched. You can run a side plug harness with more holes (I think it would have six small holes) in a socket with fewer (four small holes), but not the other way around.

Actually, the receptacle on my BT35 has additional wires for the optional charging system
So I was wondering if the plug going to the engine was the same?
